You forget PDT/ALG a few years ago, and I think more recently, CHQ & Shuttle America.
No sheet Shirlock, I'm not talking about simple 2-airline mergers! Arbitrator Bloch just did the recent Delta and Northwest SLI. There are plenty of examples of just 2-airline mergers. Those are far easier than taking 3 (or more airlines) and merging them into one list. Arbitrator Bloch will have very few examples, Eagle being one of them.
